A Broward County man is scheduled to die by lethal injection on Thursday evening while his legal team mounts a furious, multi-pronged effort to halt the execution in federal and state courts.
Richard Knight, who was convicted of the 2000 murders of Odessia Stephens and her daughter, Hanessia Mullings, faces a May 21 execution date at 6:00 p.m. ET. If carried out, it will mark the seventh execution in Florida this year and the 34th under Governor Ron DeSantis.
On Monday, Knight’s defense team escalated his case to the U.S. Supreme Court, filing a petition for writ of certiorari that challenges the constitutional validity of his death sentence. The appeal centers on the fallout from a landmark 2016 ruling, Hurst v. Florida, in which the U.S. Supreme Court struck down Florida’s capital sentencing system because it allowed judges, rather than juries, to find the facts necessary to impose a death sentence.
Following the Hurst decision, Florida courts established a cutoff date based on a 2002 legal milestone. Defendants whose sentences became final after 2002 were granted new sentencing hearings, while those whose cases concluded before that year were denied relief, despite being sentenced under the exact same struck-down framework. Knight’s attorneys argue this arbitrary dividing line denies him equal protection under the law, pointing to a recent 2024 U.S. Supreme Court case, Erlinger v. United States, as a sign that the nation’s highest court may be ready to enforce its constitutional rulings retroactively for all affected inmates.
“Florida cannot continue picking and choosing who receives constitutional protections and who does not,” said Grace Hanna, Executive Director of Floridians for Alternatives to the Death Penalty (FADP), an organization currently lobbying for a stay and a commutation to life without parole. “If a sentencing scheme was unconstitutional for some people, it was unconstitutional for everyone sentenced under it – including Richard Knight.”
Simultaneously, defense lawyers have filed a separate petition with the U.S. Supreme Court targeting Florida’s execution protocol itself. The filing argues that the state’s lethal injection guidelines violate the Eighth and Fourteenth Amendments by permitting execution teams to perform a “venous cutdown”—a surgical procedure used to access a vein—inside the death chamber without local anesthesia if standard intravenous access fails.
The petition states the surgical procedure carries severe risks, including catastrophic bleeding, collapsed lungs, air embolisms, and conscious paralysis if handled incorrectly, adding that the execution chamber at Florida State Prison is unequipped for surgical emergencies and operations remain “shrouded in secrecy.”
Meanwhile, a parallel dispute over forensic evidence is playing out before the Florida Supreme Court. Defense filings reveal that a usable, unidentified fingerprint was recovered from the blade of a bloody knife linked to the double homicide. Trial testimony confirmed the print does not match Knight, either of the victims, or anyone else tied to the investigation.
While the prosecution relied on a combination of DNA, bloodstains, and weapons to secure the original conviction, state prosecutors recently acknowledged in court that there was “no testimony of when any of the bloodstains or any of the prints were made.” Knight’s team is demanding that the Broward Sheriff’s Office run the mystery print through the national Automated Fingerprint Identification System (AFIS) to check for alternative suspects.
Herman Lindsey, executive director of Witness to Innocence and Florida’s 23rd death row exoneree, questioned the state’s rush to proceed under a cloud of forensic uncertainty.
“I was sentenced to death by the same judge, in the same courtroom, as Richard Knight. I was later exonerated, so I know what can happen when the system ignores evidence,” Lindsey said. “In a state that has more death row exonerees than any other, it’s curious that Florida is so willing to execute a man without knowing the full truth. If there’s an unidentified fingerprint on the murder weapon, the State should find out who it belongs to before carrying out an execution.”
